I've tried to install two TTF fonts, but they don't show up in FontBook.

Message in Console is:

Sandbox: FontValidator(897) deny(1) file-read-metadata /

The files were already present in ~/Library/Fonts but they had different permissions than the other files. By changing permissions -- using sudo chmod 755 blah.ttf -- and then running FontBook, everything worked.
